1974 Honda CB550K · Engine Buying guide

Planning a CB550K engine job

Piston packages, gasket assortments and oil-seal kits cover different needs. A product’s rebuild label does not establish every included part; use its written contents to decide which separate components belong in the order.

Parts to consider

1974-78 Honda CB550F / CB550K Athena Overhaul Gasket Set Athena overhaul gasket setAthena’s overhaul gasket assortment lists the 1974–78 CB550K. Its description does not itemize the supplied gaskets, so confirm the contents needed for your repair before ordering.View part 1974-78 Honda CB550F / CB550K Standard Size (58.5 mm) Piston Kit ~ Includes Piston, Rings, Pin & Clips Standard 58.5mm piston kitPiston, rings, pin and clips for one cylinder; the listing notes four kits are needed for the engine.View part Honda CB Oil Filter ~ Replaces 15410-426-010 Stock-type paper oil filterPaper filter element replacing OEM 15410-426-010; washers, O-rings and the spring are sold separately.View part

Check what the assortment actually names

The two overhaul gasket listings identify their CB550K applications without a written list of every supplied piece. The nine-piece oil-seal kit is more specific: it names the supplied seals. Compare those descriptions separately; an overhaul label alone does not establish that another product’s contents are included.

Measure before buying pistons

The piston kit specifies standard size at 58.5mm, while both ring choices identify standard applications. These listings do not offer an oversize measurement. Establish the size required by the engine being repaired before choosing rings or a piston package from this selection.

Engine questions

How many piston kits does a 1974 CB550K need?

Four. Each standard-size kit contains the piston, rings, pin and clips for one cylinder, and the listing states plainly that a four-cylinder engine needs four kits to rebuild every piston.

Which oil filter fits the 1974 CB550K?

The paper element replaces references 15410-426-010 and 15410-422-004 and includes the CB550K application. Its description offers O-rings, springs and washers separately, so check which associated components your filter service actually requires.

Do the overhaul gasket descriptions list every supplied part?

Neither overhaul listing gives an itemized list of supplied gaskets. Confirm the needed contents before choosing an assortment, and keep the separately documented nine-piece engine oil-seal kit distinct from those gasket purchases.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
